Implant, especially for the occlusion of bifurcation aneurysms

摘要

The invention relates to an implant (1) to be used for the occlusion of aneurysms in the region of vessel branches, in particular bifurcation aneurysms (A), with a mesh structure (3, 4), said implant comprising—from proximal to distal—sections (a) to (d) where
(a) is a section tapering down proximally in which the mesh structure is brought together to form one or several coupling elements (10).(b) is a fixing section by means of which the implant can be supported on the to wall of a vessel,(c) is a permeable section for the region of the vessel bifurcation, and(d) is a distal section in which the implant is expanded in comparison to section (b) and which is intended for placement into the aneurysm (A), wherein a separation zone (T1, T2) being arranged in the area of sections (c) or (d).

1. Implant (1) to be used for the occlusion of bifurcation aneurysms (A), with a mesh structure (3, 4), said implant comprising—from proximal to distal—sections (a) to (d):
(a) is a section tapering down proximally in which the mesh structure is brought together to form one or several coupling elements (10), (b) is a fixing section by means of which the implant can be supported on the wall of a vessel, (c) is a permeable section for a region of vessel bifurcation, and (d) is a distal section in which the implant is expanded in comparison to section (b) and which is intended for placement into the aneurysm (A), wherein a separation zone (T1) is arranged in between sections (c) and (d), the separation zone (T1) being provided with separation elements consisting of filaments (6) extending substantially in a plane crosswise to the implant (1), and the distal section (d) consisting of a plurality of loops (12).
